Someone else will probably chime in but from what I have read on this thread and other posts on the site, it is definitely covered by warranty. I have heard of some dealerships not wanting to do it or not installing the piece correctly so the issue comes back. I know when I told my sales guy about it, he had never heard of this problem. So I called the service deparment and they said the same thing. Hopefully I won't have an issue when I go.
